If you are getting errors saying "There is a duplicate xxx.xxx.xxx section defined", the reason this fails is because these section definitions are
already included in the root web.config on IIS server. To fix this error ,you can :
1) Change .net version and mode to match the ones that you currently have in your local development environment. To change .Net version , please go to your
Hosting Control Panel -> IIS Manager -> ASP.NET manager.
OR
2) Remove all of the duplicate sections from your web.config according to the error.
